The example of Lesson 22 understand angle relationships in triangles i that the measure of the angle given in the image attached is 65°; supplementary angles add up to 180°.
<h3>What are the angle relationships in triangles?</h3>There is the Interior angles which is known to have its both on the inside to be of parallel lines and as such, they are supplementary.
An example of Angle Pair Relationship are:
- Complementary Angles
- Supplementary Angles
- Adjacent Angles
The answer is 65° and it is a supplementary angles that can add up to 180°. Note that Two angles are called supplementary when their given measures when added together is up to 180 degrees.
